This is truly a great thread joker, so useful. I'm half for the thought you should expand it to just include your full-size arsenal, if possible. Th RX700s people ask alot, and it would be nice to have them compared to these other great cans. I got the PX200-II today, love it especially for its size, but it really makes me appreciate the RX700s even more; these don't seem like they'll be able to match up to them even after burn-in. As far as I know, these don't benefit so hugely from burn-in. Still can't believe how much sound I got out of 35 dollars. I'm loving being able to stick the PX200IIs into my pocket though.
